MAT2 (Metadata Anonymisation Toolkit 2) removes embedded metadata from images, PDFs, audio files, office documents, and more. It runs as a CLI tool or as a file-manager extension for Nautilus and Dolphin on Linux.

Our take
Metadata in ordinary files - GPS coordinates in photos, author names in PDFs, recording device in audio - is a routine privacy leak that most people never check. MAT2 handles it cleanly across a wide format range and integrates directly into Nautilus and Dolphin for right-click stripping without opening a terminal. Development has gone quiet and the repository is now archived, so treat it as stable and finished rather than actively maintained. It does the job well for Linux users; Windows and Mac users will need ExifTool or an alternative.
